Plays in general are probably the easiest form of writing to distill into stereotypes since they rely heavily on dialogue and that's bound to get repetitive when thousands of works are written. I can think of a dozen plays right now where there were similar moments of young adults arguing with relatives (usually not parents but aunts or grandmas) or someone monologuing about a death that happened offscreen but in a vague way. All of these moments can be deconstructed and I do find them repetitive if I read a few plays in a row... but I still feel like it's wholly a matter of preference. If you like those elements - sad women staring out of windows, for example - you'll like the plays.
